We describe Cu-catalyzed intermolecular alkynylation and allylation of unactivated C(sp3)–H bonds with singly occupied molecular orbital-philes (SOMO-philes) via hydrogen atom transfer (HAT). Employing N-fluoro-sulfonamide as a HAT reagent, a set of substituted alkene and alkyne compounds were synthesized in high yields with good regioselectivity and functional-group compatibility. Late-stage functionalization
我们描述了铜催化的分子间炔基化和未活化的 C(sp 3 )-H 键通过氢原子转移 (HAT) 与单占据分子轨道亲 (SOMO-philes) 的烯丙基化。采用N-氟磺酰胺作为HAT试剂,以高收率合成了一组取代的烯烃和炔烃化合物,具有良好的区域选择性和官能团相容性。还展示了天然产物和药物分子的后期功能化。
